As illustrated in Fig. 2, the bridge H is secured to the block ID by a plurality of screws [9. The blocks, bridge and base are preferably made of wood, but it is to be understood that materials other than wood may be utilized for this purpose.

In Figs. 3 and 4, a further form of the invention is illustrated, that wherein the bridge 2| is provided with a plurality of V-slots l4 and in addition is provided with a clamping element 22 which is secured to the end of the base ID by a plurality of screws 23. The clamping element-22 may be made of any spring material, and is herein illustrated as being made of hard wood which permits it to spring against the end of the base and thereby hold the ends of the strings from slipping in the slots [4. A pair of bridges 2| may be employed on both ends of the base since, when the ends of the strings are to be advanced to move the finished material forward, the material may be stretched over the top 24 of the bridge and clamped against the end of the base In by the clamping element 22.

In Figs. and 6, a further form of the invention is illustrated, that wherein a pair of spaced base elements 25 are utilized in place of the base It], for the purpose of adding additional strength to the base and for providing a space 26 therebetween in which the finished portion 21 of the article may be drawn and advanced as the work progresses.

In Fig. 7, a further form of the invention is illustrated, that wherein a pair of clamping blocks l2 is utilized, one at the end of the base [0, the other inwardly of the opposite end of the base. In such a construction, the spacing of the threads may be varied and the threads may be extended to the side edge of the blocks. This permits the operator to Work with a greater number of strings to make a wider product. I

The block l2 on the right-hand end of the base [0 is illustrated as clamping a starting block 3!] having a plurality of apertures 3| extending partially through the block for the reception of pins 32. The apertures are spaced equal distances apart and, to provide strength to the block, are disposed in rows at an angle to each other. As illustrated in Fig. 8, three loops of threads 33 are disposed over three pins 32 and the threads are knotted together. Thereafter, two of the pins are removed and inserted in two other apertures and two additional threads are looped thereover and knotted to the first group. Two of the pins are again moved to two other apertures and other loops of threads are placed thereover and knotted to the main group. This continues until all of the threads to be employed in the article are knotted together. Thereafter, the starting board is removed from the block l2, which thereafter directly clamps the knotted threads in position to be worked upon between the two blocks l2.

- In any of the constructions the threads may be readily loosened and advanced between the bridging element and the block and again clamped in position without it being necessary for the operator to remove his eyes from the work which, in intricate types of articles and designs, is found to be necessary. The knotting boards are of rugged construction and require very little time and labor for their production.

2. In a knotting board for supporting spaced threads, a pair of base elements, means for spacing said elements apart one above the other, uprights secured at each end of the base elements, and means for releasably securing threads across said uprights above said base elements.

3. In a knotting board for supporting spaced threads, a pair of base elements, means for spacing said elements apart, uprights secured at each end of the base elements, and means for releasably securing threads across said uprights above said base elements, one of said uprights being provided with a plurality of slots for spacing and securing one end of the threads.

4. In a knotting board for supporting spaced threads, a pair of base elements, means for spacing said elements apart, uprights secured at each end of the base elements, and means for releasably securing threads across said uprights above said base elements, one of said uprights being provided with a plurality of slots for spacing and securing one end of the threads, the other of said uprights being provided with a clamping plate associated with the other of said uprights for securing threads and the finished product thereon.

5. In a knotting board for supporting spaced threads, a pair of base elements, means for spacing said elements apart, uprights secured at each end of the base elements, and means for releasably securing threads across said uprights above said base elements, one of said uprights being provided with a plurality of slots for spacing and securing one end of the threads, the other of said uprights being provided with a clamping plate associated with the other of said uprights for securing the finished product thereon, said clamping plate being secured to the top of the uprightfor pressing the finished product against the top edge thereof.

6. In a knotting board for supporting spaced threads, a base, a pair of uprights on the ends of said base, and means for releasably securing threads to the top of said uprights in predetermined-spaced relation to each other, one of said 7 uprights being provided with means for spacing and securing the ends of the threads, the other of said uprights being provided with a clamping block which is drawn downwardly toward the top of the upright for clamping the finished material therebetween.

7. In a knotting board for supporting spaced threads, a base, a block at each end of the base, one extending inwardly from one edge thereof, bolts extending upwardly through said block, clamping plates disposed over the top ends of said bolts and thumb nuts on the said bolts for clamping threads between the plate and the end of the block, a second base element below said base, and spacing means between said base elements CLINTON L.
